Diodes are components commonly used in electronics as one-way path for electric current. They can also be used to rectify alternating current (AC) into direct current (DC). The single rectifier diodes, such as the VSB1545-5300M3/73 from Vishay, are used for the most general applications in current rectification. This article introduces its application field and working principles.

VSB1545-5300M3/73 Application Field

The VSB1545-5300M3/73 is a single rectifier diode with a reverse-blocking voltage of 5300V, a forward current of 15A and very low capacitance. With a high surgeforward capability, it is suitable for used in the most common applications where alternating current (AC) needs to be converted into direct current (DC). It is applicable in a large range of industrial, automotive, and consumer products and it is especially suitable for bypass circuits, free-wheeling, and power sources.

VSB1545-5300M3/73 Working Principle

The basic working principle behind diodes is quite straightforward. A single rectifier diode can be thought of as having two electrodes connected to one another by an insulating or semi-conducting material. When voltage is applied to the electrodes, current only flows in one direction, away from the negative electrode, towards the positive electrode. This is referred to as the forward bias. If the polarity of the voltage is reversed, the diode acts as an open circuit, blocking the current and acting as a short circuit. This is referred to as the reverse bias.

The VSB1545-5300M3/73 rectifier diode takes advantage of this behavior to convert AC into DC. An alternating voltage applied across the diode’s electrodes will cause current to flow through the diode in either direction depending on the polarity of the voltage. As the voltage changes, the direction of current will reverse, creating a DC voltage whose magnitude is dependent on the applied voltage’s peak value.

Conclusion

The VSB1545-5300M3/73 is a single rectifier diode used in a wide range of applications, ranging from industrial to automotive and consumer products. Its working principle is based on scanning the applied voltage to distinguish between forward bias and reverse bias, enabling the conversion of AC into DC.
